Incorrect `opcache.memory_consumption` value (returns 0) on PHP 8.5

[IndraGunawan]

What happened?

I am using the standard php.ini from https://github.com/dunglas/symfony-docker/blob/main/frankenphp/conf.d/10-app.ini and seeing an issue where opcache_get_configuration() says ['directives']['opcache.memory_consumption'] is 0, even though it is set to 256MB in my config.

Details
FrankenPHP: PHP 8.4 returns the correct value
FPM: PHP 8.5 returns the correct value
FrankenPHP: with PHP 8.5 returns 0

I noticed a similar issue in php/php-src#16927 (comment). I am opening this here as well because the behavior differs between SAPIs on the same PHP version.

How to reproduce
Set opcache.memory_consumption=256 in php.ini

<?php
var_dump(ini_get('opcache.memory_consumption')); // Shows 256
var_dump(opcache_get_configuration()['directives']['opcache.memory_consumption']); // Shows 0

Seems to be an upstream bug with ZTS in general, so let's wait it out for now.

Oh, seems like it's not getting much traction, I would fix it but I'm working on too many different things and already have a dozen PR's open. Remind me in a week or two and I'll do it.
